1openssh (1:6.7p1-5) unstable; urgency=medium
2
3 openssh-server 1:6.7p1-4 changed the default setting of AcceptEnv to list
4 a number of specific LC_FOO variables rather than the wildcard LC_*. I
5 have since been persuaded that this was a bad idea and have reverted it,
6 but it is difficult to automatically undo the change to
7 /etc/ssh/sshd_config without compounding the problem (that of modifying
8 configuration that some users did not want to be modified) further. Most
9 users who upgraded via version 1:6.7p1-4 should restore the previous value
10 of "AcceptEnv LANG LC_*" in /etc/ssh/sshd_config.

15
16 Smartcard support is now available using PKCS#11 tokens. If you were
17 previously using an unofficial build of Debian's OpenSSH package with
18 OpenSC-based smartcard support added, then note that commands like
19 'ssh-add -s 0' will no longer work; you need to use 'ssh-add -s
20 /usr/lib/opensc-pkcs11.so' instead.

24openssh (1:3.8.1p1-9) experimental; urgency=low
25
26 The ssh package has been split into openssh-client and openssh-server. If
27 you had previously requested that the sshd server should not be run, then
28 that request will still be honoured. However, the recommended approach is
29 now to remove the openssh-server package if you do not want to run sshd.
30 You can remove the old /etc/ssh/sshd_not_to_be_run marker file after doing
31 that.

35openssh (1:3.5p1-1) unstable; urgency=low
36
37 This version of OpenSSH disables the environment option for public keys by
38 default, in order to avoid certain attacks (for example, LD_PRELOAD). If
39 you are using this option in an authorized_keys file, beware that the keys
40 in question will no longer work until the option is removed.
41
42 To re-enable this option, set "PermitUserEnvironment yes" in
43 /etc/ssh/sshd_config after the upgrade is complete, taking note of the
44 warning in the sshd_config(5) manual page.

49
50 As of version 3, OpenSSH no longer uses separate files for ssh1 and ssh2
51 keys. This means the authorized_keys2 and known_hosts2 files are no longer
52 needed. They will still be read in order to maintain backward
53 compatibility.

1OpenSSH for Debian
2------------------
3
4UPGRADE ISSUES
5==============
6
7Privilege Separation
8--------------------
9
10As of 3.3, openssh has employed privilege separation to reduce the
11quantity of code that runs as root, thereby reducing the impact of
12some security holes in sshd. This now also works properly with PAM.
13
14Privilege separation is turned on by default, so, if you decide you
15want it turned off, you need to add "UsePrivilegeSeparation no" to
16/etc/ssh/sshd_config.
17
18PermitRootLogin
19---------------
20
21As of 1:6.6p1-1, new installations will be set to "PermitRootLogin
22without-password". This disables password authentication for root, foiling
23password dictionary attacks on the root user. Some sites may wish to use
24the stronger "PermitRootLogin forced-commands-only" or "PermitRootLogin no",
25but note that "PermitRootLogin no" will break setups that SSH to root with a
26forced command to take full-system backups. You can use PermitRootLogin in
27a Match block if you want finer-grained control here.
28
29For many years Debian's OpenSSH packaging used "PermitRootLogin yes", in
30line with upstream. To avoid breaking local setups, this is still true for
31installations upgraded from before 1:6.6p1-1. If you wish to change this,
32you should edit /etc/ssh/sshd_config, change it manually, and run "service
33ssh restart" as root.
34
35Disabling PermitRootLogin means that an attacker possessing credentials for
36the root account (any credentials in the case of "yes", or private key
37material in the case of "without-password") must compromise a normal user
38account rather than being able to SSH directly to root. Be careful to avoid
39a false illusion of security if you change this setting; any account you
40escalate to root from should be considered equivalent to root for the
41purposes of security against external attack. You might for example disable
42it if you know you will only ever log in as root from the physical console.
43
44Since the root account does not generally have non-password credentials
45unless you explicitly install an SSH public key in its
46~/.ssh/authorized_keys, which you presumably only do if you want to SSH to
47it, "without-password" should be a reasonable default for most sites.
48

53
54X11 Forwarding
55--------------
56
57ssh's default for ForwardX11 has been changed to ``no'' because it has
58been pointed out that logging into remote systems administered by
59untrusted people is likely to open you up to X11 attacks, so you
60should have to actively decide that you trust the remote machine's
61root, before enabling X11. I strongly recommend that you do this on a
62machine-by-machine basis, rather than just enabling it in the default
63host settings.
64
65In order for X11 forwarding to work, you need to install xauth on the
66server. In Debian this is in the xbase-clients package.
67
68As of OpenSSH 3.1, the remote $DISPLAY uses localhost by default to reduce
69the security risks of X11 forwarding. Look up X11UseLocalhost in
70sshd_config(8) if this is a problem.
71
72OpenSSH 3.8 invented ForwardX11Trusted, which when set to no causes the
73ssh client to create an untrusted X cookie so that attacks on the
74forwarded X11 connection can't become attacks on X clients on the remote
75machine. However, this has some problems in implementation - notably a
76very short timeout of the untrusted cookie - breaks large numbers of
77existing setups, and generally seems immature. The Debian package
78therefore sets the default for this option to "yes" (in ssh itself,
79rather than in ssh_config).
80
81Fallback to RSH
82---------------
83
84The default for this setting has been changed from Yes to No, for
85security reasons, and to stop the delay attempting to rsh to machines
86that don't offer the service. Simply switch it back on in either
87/etc/ssh/ssh_config or ~/.ssh/config for those machines that you need
88it for.
89
90Setgid ssh-agent and environment variables
91------------------------------------------
92
93As of version 1:3.5p1-1, ssh-agent is installed setgid to prevent ptrace()
94attacks retrieving private key material. This has the side-effect of causing
95glibc to remove certain environment variables which might have security
96implications for set-id programs, including LD_PRELOAD, LD_LIBRARY_PATH, and
97TMPDIR.
98
99If you need to set any of these environment variables, you will need to do
100so in the program exec()ed by ssh-agent. This may involve creating a small
101wrapper script.
102
103Symlink Hostname invocation
104---------------------------
105
106This version of ssh no longer includes support for invoking ssh with the
107hostname as the name of the file run. People wanting this support should
108use the ssh-argv0 script.
109
110=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
111
112OTHER ISSUES
113============
114
115/usr/bin/ssh not SUID
116---------------------
117
118Due to Debian bug #164325, RhostsRSAAuthentication can only be used if ssh
119is SUID. Until this is fixed, if that is a problem, use:
120
121 dpkg-statoverride
122
123or if that's also missing, use this:
124
125 chown root.root /usr/bin/ssh
126 chmod 04755 /usr/bin/ssh
127
128Authorization Forwarding
129------------------------
130
131Similarly, root on a remote server could make use of your ssh-agent
132(while you're logged into their machine) to obtain access to machines
133which trust your keys. This feature is therefore disabled by default.
134You should only re-enable it for those hosts (in your ~/.ssh/config or
135/etc/ssh/ssh_config) where you are confident that the remote machine
136is not a threat.
137
138Problems logging in with RSA authentication
139-------------------------------------------
140
141If you have trouble logging in with RSA authentication then the
142problem is probably caused by the fact that you have your home
143directory writable by group, as well as user (this is the default on
144Debian systems).
145
146Depending upon other settings on your system (i.e. other users being
147in your group) this could open a security hole, so you will need to
148make your home directory writable only by yourself. Run this command,
149as yourself:
150
151 chmod g-w ~/
152
153to remove group write permissions. If you use ssh-copy-id to install your
154keys, it does this for you.
155
156-L option of ssh nonfree
157------------------------
158
159non-free ssh supported the usage of the option -L to use a non privileged
160port for scp. This option will not be supported by scp from openssh.
161
162Please use instead scp -o "UsePrivilegedPort=no" as documented in the
163manpage to scp itself.
164
165Problem logging in because of TCP-Wrappers
166------------------------------------------
167
168ssh is compiled with support for tcp-wrappers. So if you can no longer
169log into your system, please check that /etc/hosts.allow and /etc/hosts.deny
170are configured so that ssh is not blocked.
171
172Kerberos support
173----------------
174
175ssh is now compiled with Kerberos support. Unfortunately, privilege
176separation is incompatible with Kerberos support for SSH protocol 1 and
177parts of the support for protocol 2; you may need to run kinit after logging
178in.
179
180Interoperability between scp and the ssh.com SSH server
181-------------------------------------------------------
182
183In version 2 and greater of the commercial SSH server produced by SSH
184Communications Security, scp was changed to use SFTP (SSH2's file transfer
185protocol) instead of the traditional rcp-over-ssh, thereby breaking
186compatibility. The OpenSSH developers regard this as a bug in the ssh.com
187server, and do not currently intend to change OpenSSH's scp to match.
188
189Workarounds for this problem are to install scp1 on the server (scp2 will
190fall back to it), to use sftp, or to use some other transfer mechanism such
191as rsync-over-ssh or tar-over-ssh.
192
193Running sshd from inittab
194-------------------------
195
196Some people find it useful to run the sshd server from inittab, to make sure
197that it always stays running. To do this, stop sshd ('/etc/init.d/ssh
198stop'), add the following line to /etc/inittab, and run 'telinit q':
199
200 ss:2345:respawn:/usr/sbin/sshd -D
201
202If you do this, note that you will need to stop sshd being started in the
203normal way ('update-rc.d ssh disable') and that you will need to restart
204this sshd manually on upgrades.
205
206Per-connection sshd instances with systemd
207------------------------------------------
208
209If you want to reconfigure systemd to listen on port 22 itself and launch an
210instance of sshd for each connection (inetd-style socket activation), then
211you can run:
212
213 systemctl stop ssh.service
214 systemctl start ssh.socket
215
216To make this permanent:
217
218 systemctl disable ssh.service
219 systemctl enable ssh.socket
220
221This may be appropriate in environments where minimal footprint is critical
222(e.g. cloud guests). Be aware that this bypasses MaxStartups, and systemd's
223MaxConnections cannot quite replace this as it cannot distinguish between
224authenticated and unauthenticated connections; see
225https://bugzilla.redhat.com/show_bug.cgi?id=963268 for more discussion.
226
227The provided ssh.socket unit file sets ListenStream=22. If you need to have
228it listen on a different address or port, then you will need to do this by
229copying /lib/systemd/system/ssh.socket to /etc/systemd/system/ssh.socket and
230modifying the ListenStream option. See systemd.socket(5) for details.

22 * New upstream release (http://www.openssh.com/txt/release-6.8):
23 - sshd(8): UseDNS now defaults to 'no'. Configurations that match
24 against the client host name (via sshd_config or authorized_keys) may
25 need to re-enable it or convert to matching against addresses.
26 - Add FingerprintHash option to ssh(1) and sshd(8), and equivalent
27 command-line flags to the other tools to control algorithm used for
28 key fingerprints. The default changes from MD5 to SHA256 and format
29 from hex to base64.
30 Fingerprints now have the hash algorithm prepended. An example of the
31 new format: SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE
32 Please note that visual host keys will also be different.
33 - ssh(1), sshd(8): Experimental host key rotation support. Add a
34 protocol extension for a server to inform a client of all its
35 available host keys after authentication has completed. The client
36 may record the keys in known_hosts, allowing it to upgrade to better
37 host key algorithms and a server to gracefully rotate its keys.
38 The client side of this is controlled by a UpdateHostkeys config
39 option (default off).
40 - ssh(1): Add a ssh_config HostbasedKeyType option to control which host
41 public key types are tried during host-based authentication.
42 - ssh(1), sshd(8): Fix connection-killing host key mismatch errors when
43 sshd offers multiple ECDSA keys of different lengths.
44 - ssh(1): When host name canonicalisation is enabled, try to parse host
45 names as addresses before looking them up for canonicalisation. Fixes
46 bz#2074 and avoids needless DNS lookups in some cases.
47 - ssh(1), ssh-keysign(8): Make ed25519 keys work for host based
48 authentication.
49 - sshd(8): SSH protocol v.1 workaround for the Meyer, et al,
50 Bleichenbacher Side Channel Attack. Fake up a bignum key before RSA
51 decryption.
52 - sshd(8): Remember which public keys have been used for authentication
53 and refuse to accept previously-used keys. This allows
54 AuthenticationMethods=publickey,publickey to require that users
55 authenticate using two _different_ public keys.
56 - sshd(8): add sshd_config HostbasedAcceptedKeyTypes and
57 PubkeyAcceptedKeyTypes options to allow sshd to control what public
58 key types will be accepted (closes: #481133). Currently defaults to
59 all.
60 - sshd(8): Don't count partial authentication success as a failure
61 against MaxAuthTries.
62 - ssh(1): Add RevokedHostKeys option for the client to allow text-file
63 or KRL-based revocation of host keys.
64 - ssh-keygen(1), sshd(8): Permit KRLs that revoke certificates by serial
65 number or key ID without scoping to a particular CA.
66 - ssh(1): Add a "Match canonical" criteria that allows ssh_config Match
67 blocks to trigger only in the second config pass.
68 - ssh(1): Add a -G option to ssh that causes it to parse its
69 configuration and dump the result to stdout, similar to "sshd -T".
70 - ssh(1): Allow Match criteria to be negated. E.g. "Match !host".
71 - ssh-keyscan(1): ssh-keyscan has been made much more robust against
72 servers that hang or violate the SSH protocol (closes: #241119).
73 - ssh(1), ssh-keygen(1): Fix regression bz#2306: Key path names were
74 being lost as comment fields (closes: #787776).
75 - ssh(1): Allow ssh_config Port options set in the second config parse
76 phase to be applied (they were being ignored; closes: #774369).
77 - ssh(1): Tweak config re-parsing with host canonicalisation - make the
78 second pass through the config files always run when host name
79 canonicalisation is enabled (and not whenever the host name changes)
80 - ssh(1): Fix passing of wildcard forward bind addresses when connection
81 multiplexing is in use.
82 - ssh-keygen(1): Fix broken private key conversion from non-OpenSSH
83 formats.
84 - ssh-keygen(1): Fix KRL generation bug when multiple CAs are in use.
85 * New upstream release (http://www.openssh.com/txt/release-6.9):
86 - CVE-2015-5352: ssh(1): When forwarding X11 connections with
87 ForwardX11Trusted=no, connections made after ForwardX11Timeout expired
88 could be permitted and no longer subject to XSECURITY restrictions
89 because of an ineffective timeout check in ssh(1) coupled with "fail
90 open" behaviour in the X11 server when clients attempted connections
91 with expired credentials (closes: #790798). This problem was reported
92 by Jann Horn.
93 - SECURITY: ssh-agent(1): Fix weakness of agent locking (ssh-add -x) to
94 password guessing by implementing an increasing failure delay, storing
95 a salted hash of the password rather than the password itself and
96 using a timing-safe comparison function for verifying unlock attempts.
97 This problem was reported by Ryan Castellucci.
98 - sshd(8): Support admin-specified arguments to AuthorizedKeysCommand
99 (closes: #740494).
100 - sshd(8): Add AuthorizedPrincipalsCommand that allows retrieving
101 authorized principals information from a subprocess rather than a
102 file.
103 - ssh(1), ssh-add(1): Support PKCS#11 devices with external PIN entry
104 devices.
105 - ssh-keygen(1): Support "ssh-keygen -lF hostname" to search known_hosts
106 and print key hashes rather than full keys.
107 - ssh-agent(1): Add -D flag to leave ssh-agent in foreground without
108 enabling debug mode.
109 - ssh(1), sshd(8): Deprecate legacy SSH2_MSG_KEX_DH_GEX_REQUEST_OLD
110 message and do not try to use it against some 3rd-party SSH
111 implementations that use it (older PuTTY, WinSCP).
112 - ssh(1), sshd(8): Cap DH-GEX group size at 4Kbits for Cisco
113 implementations as some would fail when attempting to use group sizes
114 >4K (closes: #740307, LP: #1287222).
115 - ssh(1): Fix out-of-bound read in EscapeChar configuration option
116 parsing.
117 - sshd(8): Fix application of PermitTunnel, LoginGraceTime,
118 AuthenticationMethods and StreamLocalBindMask options in Match blocks.
119 - ssh(1), sshd(8): Improve disconnection message on TCP reset.
120 - ssh(1): Remove failed remote forwards established by multiplexing from
121 the list of active forwards.
122 - sshd(8): Make parsing of authorized_keys "environment=" options
123 independent of PermitUserEnv being enabled.
124 - sshd(8): Fix post-auth crash with permitopen=none (closes: #778807).
125 - ssh(1), ssh-add(1), ssh-keygen(1): Allow new-format private keys to be
126 encrypted with AEAD ciphers.
127 - ssh(1): Allow ListenAddress, Port and AddressFamily configuration
128 options to appear in any order.
129 - sshd(8): Check for and reject missing arguments for VersionAddendum
130 and ForceCommand.
131 - ssh(1), sshd(8): Don't treat unknown certificate extensions as fatal.
132 - ssh-keygen(1): Make stdout and stderr output consistent.
133 - ssh(1): Mention missing DISPLAY environment in debug log when X11
134 forwarding requested.
135 - sshd(8): Correctly record login when UseLogin is set.
136 - sshd(8): Add some missing options to sshd -T output and fix output of
137 VersionAddendum and HostCertificate.
138 - Document and improve consistency of options that accept a "none"
139 argument: TrustedUserCAKeys, RevokedKeys, AuthorizedPrincipalsFile.
140 - ssh(1): Include remote username in debug output.
141 - sshd(8): Avoid compatibility problem with some versions of Tera Term,
142 which would crash when they received the hostkeys notification message
143 (hostkeys-00@openssh.com).
144 - sshd(8): Mention ssh-keygen -E as useful when comparing legacy MD5
145 host key fingerprints.
146 - ssh(1): Clarify pseudo-terminal request behaviour and make manual
147 language consistent.
148 - ssh(1): Document that the TERM environment variable is not subject to
149 SendEnv and AcceptEnv; bz#2386
150 - sshd(8): Format UsePAM setting when using sshd -T (closes: #767648).
151 - moduli(5): Update DH-GEX moduli (closes: #787037).
152 * There are some things I want to fix before upgrading to 7.0p1, though I
153 intend to do that soon. In the meantime, backport some patches, mainly
154 to fix security issues:
155 - SECURITY: sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be
156 world-writable. Local attackers may be able to write arbitrary
157 messages to logged-in users, including terminal escape sequences.
158 Reported by Nikolay Edigaryev.
159 - SECURITY: sshd(8): Fixed a privilege separation weakness related to
160 PAM support. Attackers who could successfully compromise the
161 pre-authentication process for remote code execution and who had valid
162 credentials on the host could impersonate other users. Reported by
163 Moritz Jodeit.
164 - SECURITY: sshd(8): Fixed a use-after-free bug related to PAM support
165 that was reachable by attackers who could compromise the
166 pre-authentication process for remote code execution (closes:
167 #795711). Also reported by Moritz Jodeit.
168 - CVE-2015-5600: sshd(8): Fix circumvention of MaxAuthTries using
169 keyboard-interactive authentication (closes: #793616). By specifying
170 a long, repeating keyboard-interactive "devices" string, an attacker
171 could request the same authentication method be tried thousands of
172 times in a single pass. The LoginGraceTime timeout in sshd(8) and any
173 authentication failure delays implemented by the authentication
174 mechanism itself were still applied. Found by Kingcope.
175 - Let principals-command.sh work for noexec /var/run.
176 * Thanks to Jakub Jelen of Red Hat for Fedora's rebased version of the
177 GSSAPI key exchange patch.
178 * Document the Debian-specific change to the default value of
179 ForwardX11Trusted in ssh(1) (closes: #781469).

236
237 * New upstream release (http://www.openssh.com/txt/release-6.7):
238 - sshd(8): The default set of ciphers and MACs has been altered to
239 remove unsafe algorithms. In particular, CBC ciphers and arcfour* are
240 disabled by default. The full set of algorithms remains available if
241 configured explicitly via the Ciphers and MACs sshd_config options.
242 - ssh(1), sshd(8): Add support for Unix domain socket forwarding. A
243 remote TCP port may be forwarded to a local Unix domain socket and
244 vice versa or both ends may be a Unix domain socket (closes: #236718).
245 - ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for ED25519
246 key types.
247 - sftp(1): Allow resumption of interrupted uploads.
248 - ssh(1): When rekeying, skip file/DNS lookups of the hostkey if it is
249 the same as the one sent during initial key exchange.
250 - sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind addresses
251 when GatewayPorts=no; allows client to choose address family.
252 - sshd(8): Add a sshd_config PermitUserRC option to control whether
253 ~/.ssh/rc is executed, mirroring the no-user-rc authorized_keys
254 option.
255 - ssh(1): Add a %C escape sequence for LocalCommand and ControlPath that
256 expands to a unique identifier based on a hash of the tuple of (local
257 host, remote user, hostname, port). Helps avoid exceeding miserly
258 pathname limits for Unix domain sockets in multiplexing control paths.
259 - sshd(8): Make the "Too many authentication failures" message include
260 the user, source address, port and protocol in a format similar to the
261 authentication success / failure messages.
262 - Use CLOCK_BOOTTIME in preference to CLOCK_MONOTONIC when it is
263 available. It considers time spent suspended, thereby ensuring
264 timeouts (e.g. for expiring agent keys) fire correctly (closes:
265 #734553).
266 - Use prctl() to prevent sftp-server from accessing
267 /proc/self/{mem,maps}.
268 * Restore TCP wrappers support, removed upstream in 6.7. It is true that
269 dropping this reduces preauth attack surface in sshd. On the other
270 hand, this support seems to be quite widely used, and abruptly dropping
271 it (from the perspective of users who don't read openssh-unix-dev) could
272 easily cause more serious problems in practice. It's not entirely clear
273 what the right long-term answer for Debian is, but it at least probably
274 doesn't involve dropping this feature shortly before a freeze.
275 * Replace patch to disable OpenSSL version check with an updated version
276 of Kurt Roeckx's patch from #732940 to just avoid checking the status
277 field.
278 * Build-depend on a new enough dpkg-dev for dpkg-buildflags, rather than
279 simply a new enough dpkg.
280 * Simplify debian/rules using /usr/share/dpkg/buildflags.mk.
281 * Use Package-Type rather than XC-Package-Type, now that it is an official
282 field.
283 * Run a subset of the upstream regression test suite at package build
284 time, and the rest of it under autopkgtest.

431 * Clarify socket activation mode in README.Debian, as suggested by Uoti
432 Urpala.
433 * Stop claiming that "Protocol 2" is a Debian-specific default; this has
434 been upstream's default since 5.4p1.
435 * Avoid stdout noise from which(1) on purge of openssh-client.
436 * Fix sysvinit->systemd transition code to cope with still-running
437 sysvinit jobs being considered active by systemd (thanks, Uoti Urpala
438 and Michael Biebl).
439 * Bump guard version for sysvinit->systemd transition to 1:6.5p1-3; we may
440 have got it wrong before, and it's fairly harmless to repeat it.
441 * Remove tests for whether /dev/null is a character device from the
442 Upstart job and the systemd service files; it's there to avoid a
443 confusing failure mode in daemon(), but with modern init systems we use
444 the -D option to suppress daemonisation anyway.
445 * Refer to /usr/share/common-licenses/GPL-2 in debian/copyright (for the
446 Debian patch) rather than plain GPL.
447 * Drop some very old Conflicts and Replaces (ssh (<< 1:3.8.1p1-9),
448 rsh-client (<< 0.16.1-1), ssh-krb5 (<< 1:4.3p2-7), ssh-nonfree (<< 2),
449 and openssh-client (<< 1:3.8.1p1-11)). These all relate to pre-etch
450 versions, for which we no longer have maintainer script code, and per
451 policy they would have to become Breaks nowadays anyway.
452 * Policy version 3.9.5.
453 * Drop unnecessary -1 in zlib1g Build-Depends version.
454 * Tweak dh_systemd_enable invocations to avoid lots of error noise.

468
469 * New upstream release (http://www.openssh.com/txt/release-6.5,
470 LP: #1275068):
471 - ssh(1): Add support for client-side hostname canonicalisation using a
472 set of DNS suffixes and rules in ssh_config(5). This allows
473 unqualified names to be canonicalised to fully-qualified domain names
474 to eliminate ambiguity when looking up keys in known_hosts or checking
475 host certificate names (closes: #115286).
476 * Switch to git; adjust Vcs-* fields.
477 * Convert to git-dpm, and drop source package documentation associated
478 with the old bzr/quilt patch handling workflow.
479 * Drop ssh-vulnkey and the associated ssh/ssh-add/sshd integration code,
480 leaving only basic configuration file compatibility, since it has been
481 nearly six years since the original vulnerability and this code is not
482 likely to be of much value any more (closes: #481853, #570651). See
483 https://lists.debian.org/debian-devel/2013/09/msg00240.html for my full
484 reasoning.
485 * Add OpenPGP signature checking configuration to watch file (thanks,
486 Daniel Kahn Gillmor; closes: #732441).
487 * Add the pam_keyinit session module, to create a new session keyring on
488 login (closes: #734816).
489 * Incorporate default path changes from shadow 1:4.0.18.1-8, removing
490 /usr/bin/X11 (closes: #644521).
491 * Generate ED25519 host keys on fresh installations. Upgraders who wish
492 to add such host keys should manually add 'HostKey
493 /etc/ssh/ssh_host_ed25519_key' to /etc/ssh/sshd_config and run
494 'ssh-keygen -q -f /etc/ssh/ssh_host_ed25519_key -N "" -t ed25519'.
495 * Drop long-obsolete "SSH now uses protocol 2 by default" section from
496 README.Debian.
497 * Add systemd support (thanks, Sven Joachim; closes: #676830).

511 * New upstream release. Important changes:
512 - 6.3/6.3p1 (http://www.openssh.com/txt/release-6.3):
513 + sftp(1): add support for resuming partial downloads using the
514 "reget" command and on the sftp commandline or on the "get"
515 commandline using the "-a" (append) option (closes: #158590).
516 + ssh(1): add an "IgnoreUnknown" configuration option to selectively
517 suppress errors arising from unknown configuration directives
518 (closes: #436052).
519 + sftp(1): update progressmeter when data is acknowledged, not when
520 it's sent (partially addresses #708372).
521 + ssh(1): do not fatally exit when attempting to cleanup multiplexing-
522 created channels that are incompletely opened (closes: #651357).
523 - 6.4/6.4p1 (http://www.openssh.com/txt/release-6.4):
524 + CVE-2013-4548: sshd(8): fix a memory corruption problem triggered
525 during rekeying when an AES-GCM cipher is selected (closes:
526 #729029). Full details of the vulnerability are available at:
527 http://www.openssh.com/txt/gcmrekey.adv
528 * When running under Upstart, only consider the daemon started once it is
529 ready to accept connections (by raising SIGSTOP at that point and using
530 "expect stop").

568 * If the running init daemon is Upstart, then, on the first upgrade to
569 this version, check whether sysvinit is still managing sshd; if so,
570 manually stop it so that it can be restarted under upstart. We do this
571 near the end of the postinst, so it shouldn't result in any appreciable
572 extra window where sshd is not running during upgrade.

575
576openssh (1:6.2p2-2) unstable; urgency=low
577
578 * Change start condition of Upstart job to be just the standard "runlevel
579 [2345]", rather than "filesystem or runlevel [2345]"; the latter makes
580 it unreasonably difficult to ensure that urandom starts before ssh, and
581 is not really necessary since one of static-network-up and failsafe-boot
582 is guaranteed to happen and will trigger entry to the default runlevel,
583 and we don't care about ssh starting before the network (LP: #1098299).
584 * Drop conffile handling for direct upgrades from pre-split ssh package;
585 this was originally added in 1:4.3p2-7 / 1:4.3p2-8, and contained a
586 truly ghastly hack around a misbehaviour in sarge's dpkg. Since this is
587 now four Debian releases ago, we can afford to drop this and simplify
588 the packaging.
589 * Remove ssh/use_old_init_script, which was a workaround for a very old
590 bug in /etc/init.d/ssh. If anyone has ignored this for >10 years then
591 they aren't going to be convinced now (closes: #214182).
592 * Remove support for upgrading directly from ssh-nonfree.
593 * Remove lots of maintainer script support for direct upgrades from
594 pre-etch (three releases before current stable).
595 * Add #DEBHELPER# tokens to openssh-client.postinst and
596 openssh-server.postinst.
597 * Replace old manual conffile handling code with dpkg-maintscript-helper,
598 via dh_installdeb.
599 * Switch to new unified layout for Upstart jobs as documented in
600 https://wiki.ubuntu.com/UpstartCompatibleInitScripts: the init script
601 checks for a running Upstart, and we now let dh_installinit handle most
602 of the heavy lifting in maintainer scripts. Ubuntu users should be
603 essentially unaffected except that sshd may no longer start
604 automatically in chroots if the running Upstart predates 0.9.0; but the
605 main goal is simply not to break when openssh-server is installed in a
606 chroot.
607 * Remove the check for vulnerable host keys; this was first added five
608 years ago, and everyone should have upgraded through a version that
609 applied these checks by now. The ssh-vulnkey tool and the blacklisting
610 support in sshd are still here, at least for the moment.
611 * This removes the last of our uses of debconf (closes: #221531).
612 * Use the pam_loginuid session module (thanks, Laurent Bigonville; closes:
613 #677440, LP: #1067779).
614 * Bracket our session stack with calls to pam_selinux close/open (thanks,
615 Laurent Bigonville; closes: #679458).
616 * Fix dh_builddeb invocation so that we really use xz compression for
617 binary packages, as intended since 1:6.1p1-2.

884 * New upstream release (http://www.openssh.org/txt/release-5.7):
885 - Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
886 and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA
887 offer better performance than plain DH and DSA at the same equivalent
888 symmetric key length, as well as much shorter keys.
889 - sftp(1)/sftp-server(8): add a protocol extension to support a hard
890 link operation. It is available through the "ln" command in the
891 client. The old "ln" behaviour of creating a symlink is available
892 using its "-s" option or through the preexisting "symlink" command.
893 - scp(1): Add a new -3 option to scp: Copies between two remote hosts
894 are transferred through the local host (closes: #508613).
895 - ssh(1): "atomically" create the listening mux socket by binding it on
896 a temporary name and then linking it into position after listen() has
897 succeeded. This allows the mux clients to determine that the server
898 socket is either ready or stale without races (closes: #454784).
899 Stale server sockets are now automatically removed (closes: #523250).
900 - ssh(1): install a SIGCHLD handler to reap expired child process
901 (closes: #594687).
902 - ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent
903 temporary directories (closes: #357469, although only if you arrange
904 for ssh-agent to actually see $TMPDIR since the setgid bit will cause
905 it to be stripped off).
906 * Update to current GSSAPI patch from
907 http://www.sxw.org.uk/computing/patches/openssh-5.7p1-gsskex-all-20110125.patch:
908 - Add GSSAPIServerIdentity option.
909 * Generate ECDSA host keys on fresh installations. Upgraders who wish to
910 add such host keys should manually add 'HostKey
911 /etc/ssh/ssh_host_ecdsa_key' to /etc/ssh/sshd_config and run 'ssh-keygen
912 -q -f /etc/ssh/ssh_host_ecdsa_key -N "" -t ecdsa'.
913 * Build-depend on libssl-dev (>= 0.9.8g) to ensure sufficient ECC support.
914 * Backport SELinux build fix from CVS.
915 * Rearrange selinux-role.patch so that it links properly given this
916 SELinux build fix.

1034 * New upstream release (LP: #535029).
1035 - After a transition period of about 10 years, this release disables SSH
1036 protocol 1 by default. Clients and servers that need to use the
1037 legacy protocol must explicitly enable it in ssh_config / sshd_config
1038 or on the command-line.
1039 - Remove the libsectok/OpenSC-based smartcard code and add support for
1040 PKCS#11 tokens. This support is enabled by default in the Debian
1041 packaging, since it now doesn't involve additional library
1042 dependencies (closes: #231472, LP: #16918).
1043 - Add support for certificate authentication of users and hosts using a
1044 new, minimal OpenSSH certificate format (closes: #482806).
1045 - Added a 'netcat mode' to ssh(1): "ssh -W host:port ...".
1046 - Add the ability to revoke keys in sshd(8) and ssh(1). (For the Debian
1047 package, this overlaps with the key blacklisting facility added in
1048 openssh 1:4.7p1-9, but with different file formats and slightly
1049 different scopes; for the moment, I've roughly merged the two.)
1050 - Various multiplexing improvements, including support for requesting
1051 port-forwardings via the multiplex protocol (closes: #360151).
1052 - Allow setting an explicit umask on the sftp-server(8) commandline to
1053 override whatever default the user has (closes: #496843).
1054 - Many sftp client improvements, including tab-completion, more options,
1055 and recursive transfer support for get/put (LP: #33378). The old
1056 mget/mput commands never worked properly and have been removed
1057 (closes: #270399, #428082).
1058 - Do not prompt for a passphrase if we fail to open a keyfile, and log
1059 the reason why the open failed to debug (closes: #431538).
1060 - Prevent sftp from crashing when given a "-" without a command. Also,
1061 allow whitespace to follow a "-" (closes: #531561).
1062
1063 * Fix 'debian/rules quilt-setup' to avoid writing .orig files if some
1064 patches apply with offsets.
1065 * Include debian/ssh-askpass-gnome.png in the Debian tarball now that
1066 we're using a source format that permits this, rather than messing
1067 around with uudecode.
1068 * Drop compatibility with the old gssapi mechanism used in ssh-krb5 <<
1069 3.8.1p1-1. Simon Wilkinson refused this patch since the old gssapi
1070 mechanism was removed due to a serious security hole, and since these
1071 versions of ssh-krb5 are no longer security-supported by Debian I don't
1072 think there's any point keeping client compatibility for them.
1073 * Fix substitution of ETC_PAM_D_SSH, following the rename in 1:4.7p1-4.
1074 * Hardcode the location of xauth to /usr/bin/xauth rather than
1075 /usr/bin/X11/xauth (thanks, Aron Griffis; closes: #575725, LP: #8440).
1076 xauth no longer depends on x11-common, so we're no longer guaranteed to
1077 have the /usr/bin/X11 symlink available. I was taking advantage of the
1078 /usr/bin/X11 symlink to smooth X's move to /usr/bin, but this is far
1079 enough in the past now that it's probably safe to just use /usr/bin.
1080 * Remove SSHD_OOM_ADJUST configuration. sshd now unconditionally makes
1081 itself non-OOM-killable, and doesn't require configuration to avoid log
1082 spam in virtualisation containers (closes: #555625).
1083 * Drop Debian-specific removal of OpenSSL version check. Upstream ignores
1084 the two patchlevel nybbles now, which is sufficient to address the
1085 original reason this change was introduced, and it appears that any
1086 change in the major/minor/fix nybbles would involve a new libssl package
1087 name. (We'd still lose if the status nybble were ever changed, but that
1088 would mean somebody had packaged a development/beta version rather than
1089 a proper release, which doesn't appear to be normal practice.)
1090 * Drop most of our "LogLevel SILENT" (-qq) patch. This was originally
1091 introduced to match the behaviour of non-free SSH, in which -q does not
1092 suppress fatal errors, but matching the behaviour of OpenSSH upstream is
1093 much more important nowadays. We no longer document that -q does not
1094 suppress fatal errors (closes: #280609). Migrate "LogLevel SILENT" to
1095 "LogLevel QUIET" in sshd_config on upgrade.
1096 * Policy version 3.8.4:
1097 - Add a Homepage field.

1168 - Change the default cipher order to prefer the AES CTR modes and the
1169 revised "arcfour256" mode to CBC mode ciphers that are susceptible to
1170 CPNI-957037 "Plaintext Recovery Attack Against SSH".
1171 - Add countermeasures to mitigate CPNI-957037-style attacks against the
1172 SSH protocol's use of CBC-mode ciphers. Upon detection of an invalid
1173 packet length or Message Authentication Code, ssh/sshd will continue
1174 reading up to the maximum supported packet length rather than
1175 immediately terminating the connection. This eliminates most of the
1176 known differences in behaviour that leaked information about the
1177 plaintext of injected data which formed the basis of this attack
1178 (closes: #506115, LP: #379329).
1179 - ForceCommand directive now accepts commandline arguments for the

1184 SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to
1185 avoid triggering 'Non-public channel' error messages on sshd(8) in
1186 openssh-5.1.
1187 - Avoid printing 'Non-public channel' warnings in sshd(8), since the

1274 - packet_disconnect() on padding error, too. Should reduce the success

1276 * Check that /var/run/sshd.pid exists and that the process ID listed there
1277 corresponds to sshd before running '/etc/init.d/ssh reload' from if-up
1278 script; SIGHUP is racy if called at boot before sshd has a chance to
1279 install its signal handler, but fortunately the pid file is written
1280 after that which lets us avoid the race (closes: #502444).
1281 * While the above is a valuable sanity-check, it turns out that it doesn't

1323
1324 * New upstream release (closes: #474301). Important changes not previously
1325 backported to 4.7p1:
1326 - 4.9/4.9p1 (http://www.openssh.com/txt/release-4.9):
1327 + Added chroot(2) support for sshd(8), controlled by a new option
1328 "ChrootDirectory" (closes: #139047, LP: #24777).
1329 + Linked sftp-server(8) into sshd(8). The internal sftp server is used
1330 when the command "internal-sftp" is specified in a Subsystem or
1331 ForceCommand declaration. When used with ChrootDirectory, the
1332 internal sftp server requires no special configuration of files
1333 inside the chroot environment.
1334 + Added a protocol extension method "posix-rename@openssh.com" for
1335 sftp-server(8) to perform POSIX atomic rename() operations; sftp(1)
1336 prefers this if available (closes: #308561).
1337 + Removed the fixed limit of 100 file handles in sftp-server(8).
1338 + ssh(8) will now skip generation of SSH protocol 1 ephemeral server
1339 keys when in inetd mode and protocol 2 connections are negotiated.
1340 This speeds up protocol 2 connections to inetd-mode servers that
1341 also allow Protocol 1.
1342 + Accept the PermitRootLogin directive in a sshd_config(5) Match
1343 block. Allows for, e.g. permitting root only from the local network.
1344 + Reworked sftp(1) argument splitting and escaping to be more
1345 internally consistent (i.e. between sftp commands) and more
1346 consistent with sh(1). Please note that this will change the
1347 interpretation of some quoted strings, especially those with
1348 embedded backslash escape sequences.
1349 + Support "Banner=none" in sshd_config(5) to disable sending of a
1350 pre-login banner (e.g. in a Match block).
1351 + ssh(1) ProxyCommands are now executed with $SHELL rather than
1352 /bin/sh.
1353 + ssh(1)'s ConnectTimeout option is now applied to both the TCP
1354 connection and the SSH banner exchange (previously it just covered
1355 the TCP connection). This allows callers of ssh(1) to better detect
1356 and deal with stuck servers that accept a TCP connection but don't
1357 progress the protocol, and also makes ConnectTimeout useful for
1358 connections via a ProxyCommand.
1359 + scp(1) incorrectly reported "stalled" on slow copies (closes:
1360 #140828).
1361 + scp(1) date underflow for timestamps before epoch.
1362 + ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS,
1363 instead of the current standard RRSIG.
1364 + Correctly drain ACKs when a sftp(1) upload write fails midway,
1365 avoids a fatal() exit from what should be a recoverable condition.
1366 + Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh-keygen -HF
1367 hostname") to not include any IP address in the data to be hashed.
1368 + Make ssh(1) skip listening on the IPv6 wildcard address when a
1369 binding address of 0.0.0.0 is used against an old SSH server that
1370 does not support the RFC4254 syntax for wildcard bind addresses.
1371 + Enable IPV6_V6ONLY socket option on sshd(8) listen socket, as is
1372 already done for X11/TCP forwarding sockets (closes: #439661).
1373 + Fix FD leak that could hang a ssh(1) connection multiplexing master.
1374 + Make ssh(1) -q option documentation consistent with reality.
1375 + Fixed sshd(8) PAM support not calling pam_session_close(), or
1376 failing to call it with root privileges (closes: #372680).
1377 + Fix activation of OpenSSL engine support when requested in configure
1378 (LP: #119295).
1379 + Cache SELinux status earlier so we know if it's enabled after a
1380 chroot (LP: #237557).
1381 - 5.1/5.1p1 (http://www.openssh.com/txt/release-5.1):
1382 + Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1)
1383 and ssh-keygen(1). Visual fingerprint display is controlled by a new
1384 ssh_config(5) option "VisualHostKey". The intent is to render SSH
1385 host keys in a visual form that is amenable to easy recall and
1386 rejection of changed host keys.
1387 + sshd_config(5) now supports CIDR address/masklen matching in "Match
1388 address" blocks, with a fallback to classic wildcard matching.
1389 + sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys
1390 from="..." restrictions, also with a fallback to classic wildcard
1391 matching.
1392 + Added an extended test mode (-T) to sshd(8) to request that it write
1393 its effective configuration to stdout and exit. Extended test mode
1394 also supports the specification of connection parameters (username,
1395 source address and hostname) to test the application of
1396 sshd_config(5) Match rules.
1397 + ssh(1) now prints the number of bytes transferred and the overall
1398 connection throughput for SSH protocol 2 sessions when in verbose
1399 mode (previously these statistics were displayed for protocol 1
1400 connections only).
1401 + sftp-server(8) now supports extension methods statvfs@openssh.com
1402 and fstatvfs@openssh.com that implement statvfs(2)-like operations.
1403 + sftp(1) now has a "df" command to the sftp client that uses the
1404 statvfs@openssh.com to produce a df(1)-like display of filesystem
1405 space and inode utilisation (requires statvfs@openssh.com support on
1406 the server).
1407 + Added a MaxSessions option to sshd_config(5) to allow control of the
1408 number of multiplexed sessions supported over a single TCP
1409 connection. This allows increasing the number of allowed sessions
1410 above the previous default of 10, disabling connection multiplexing
1411 (MaxSessions=1) or disallowing login/shell/subsystem sessions
1412 entirely (MaxSessions=0).
1413 + Added a no-more-sessions@openssh.com global request extension that
1414 is sent from ssh(1) to sshd(8) when the client knows that it will
1415 never request another session (i.e. when session multiplexing is
1416 disabled). This allows a server to disallow further session requests
1417 and terminate the session in cases where the client has been
1418 hijacked.
1419 + ssh-keygen(1) now supports the use of the -l option in combination
1420 with -F to search for a host in ~/.ssh/known_hosts and display its
1421 fingerprint.
1422 + ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of
1423 "rsa1" (LP: #129794).
1424 + Added an AllowAgentForwarding option to sshd_config(8) to control
1425 whether authentication agent forwarding is permitted. Note that this
1426 is a loose control, as a client may install their own unofficial
1427 forwarder.
1428 + ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when
1429 receiving network data, resulting in a ~10% speedup.
1430 + ssh(1) and sshd(8) will now try additional addresses when connecting
1431 to a port forward destination whose DNS name resolves to more than
1432 one address. The previous behaviour was to try the only first
1433 address and give up if that failed.
1434 + ssh(1) and sshd(8) now support signalling that channels are
1435 half-closed for writing, through a channel protocol extension
1436 notification "eow@openssh.com". This allows propagation of closed
1437 file descriptors, so that commands such as "ssh -2 localhost od
1438 /bin/ls | true" do not send unnecessary data over the wire.
1439 + sshd(8): increased the default size of ssh protocol 1 ephemeral keys
1440 from 768 to 1024 bits.
1441 + When ssh(1) has been requested to fork after authentication ("ssh
1442 -f") with ExitOnForwardFailure enabled, delay the fork until after
1443 replies for any -R forwards have been seen. Allows for robust
1444 detection of -R forward failure when using -f.
1445 + "Match group" blocks in sshd_config(5) now support negation of
1446 groups. E.g. "Match group staff,!guests".
1447 + sftp(1) and sftp-server(8) now allow chmod-like operations to set
1448 set[ug]id/sticky bits.
1449 + The MaxAuthTries option is now permitted in sshd_config(5) match
1450 blocks.
1451 + Multiplexed ssh(1) sessions now support a subset of the ~ escapes
1452 that are available to a primary connection.
1453 + ssh(1) connection multiplexing will now fall back to creating a new
1454 connection in most error cases (closes: #352830).
1455 + Make ssh(1) deal more gracefully with channel requests that fail.
1456 Previously it would optimistically assume that requests would always
1457 succeed, which could cause hangs if they did not (e.g. when the
1458 server runs out of file descriptors).
1459 + ssh(1) now reports multiplexing errors via the multiplex slave's
1460 stderr where possible (subject to LogLevel in the mux master).
1461 + Fixed an UMAC alignment problem that manifested on Itanium
1462 platforms.
1463 * Remove our local version of moduli(5) now that there's one upstream.
1464 * Say "GTK+" rather than "GTK" in ssh-askpass-gnome's description.
1465 * Add lintian overrides for empty /usr/share/doc/openssh-client
1466 directories in openssh-server and ssh (necessary due to being symlink
1467 targets).
1468 * Merge from Ubuntu:
1469 - Add 'status' action to openssh-server init script, requiring lsb-base
1470 (>= 3.2-13) (thanks, Dustin Kirkland).

1482 temporarily, use 'ssh -o UseBlacklistedKeys=yes'; there is no override
1483 for the blacklist check in ssh-add.

1704 * New upstream release (closes: #453367).
1705 - CVE-2007-4752: Prevent ssh(1) from using a trusted X11 cookie if
1706 creation of an untrusted cookie fails; found and fixed by Jan Pechanec
1707 (closes: #444738).
1708 - sshd(8) in new installations defaults to SSH Protocol 2 only. Existing
1709 installations are unchanged.
1710 - The SSH channel window size has been increased, and both ssh(1)
1711 sshd(8) now send window updates more aggressively. These improves
1712 performance on high-BDP (Bandwidth Delay Product) networks.
1713 - ssh(1) and sshd(8) now preserve MAC contexts between packets, which
1714 saves 2 hash calls per packet and results in 12-16% speedup for
1715 arcfour256/hmac-md5.
1716 - A new MAC algorithm has been added, UMAC-64 (RFC4418) as
1717 "umac-64@openssh.com". UMAC-64 has been measured to be approximately
1718 20% faster than HMAC-MD5.
1719 - Failure to establish a ssh(1) TunnelForward is now treated as a fatal
1720 error when the ExitOnForwardFailure option is set.
1721 - ssh(1) returns a sensible exit status if the control master goes away
1722 without passing the full exit status.
1723 - When using a ProxyCommand in ssh(1), set the outgoing hostname with
1724 gethostname(2), allowing hostbased authentication to work.
1725 - Make scp(1) skip FIFOs rather than hanging (closes: #246774).
1726 - Encode non-printing characters in scp(1) filenames. These could cause
1727 copies to be aborted with a "protocol error".
1728 - Handle SIGINT in sshd(8) privilege separation child process to ensure
1729 that wtmp and lastlog records are correctly updated.
1730 - Report GSSAPI mechanism in errors, for libraries that support multiple
1731 mechanisms.
1732 - Improve documentation for ssh-add(1)'s -d option.
1733 - Rearrange and tidy GSSAPI code, removing server-only code being linked
1734 into the client.
1735 - Delay execution of ssh(1)'s LocalCommand until after all forwardings
1736 have been established.
1737 - In scp(1), do not truncate non-regular files.
1738 - Improve exit message from ControlMaster clients.
1739 - Prevent sftp-server(8) from reading until it runs out of buffer space,
1740 whereupon it would exit with a fatal error (closes: #365541).
1741 - pam_end() was not being called if authentication failed
1742 (closes: #405041).
1743 - Manual page datestamps updated (closes: #433181).
1744 * Install the OpenSSH FAQ in /usr/share/doc/openssh-client.
1745 - Includes documentation on copying files with colons using scp

1750 * Refactor debian/rules configure and make invocations to make development
1751 easier.

1753 * Update moduli(5) to revision 1.11 from OpenBSD CVS.
1754 * Document the non-default options we set as standard in ssh_config(5) and

1756 * Recode LICENCE to UTF-8 when concatenating it to debian/copyright.
1757 * Override desktop-file-but-no-dh_desktop-call lintian warning; the
1758 .desktop file is intentionally not installed (see 1:3.8.1p1-10).

1854
1855 * New upstream release (closes: #395507, #397961, #420035). Important
1856 changes not previously backported to 4.3p2:
1857 - 4.4/4.4p1 (http://www.openssh.org/txt/release-4.4):
1858 + On portable OpenSSH, fix a GSSAPI authentication abort that could be
1859 used to determine the validity of usernames on some platforms.
1860 + Implemented conditional configuration in sshd_config(5) using the
1861 "Match" directive. This allows some configuration options to be
1862 selectively overridden if specific criteria (based on user, group,
1863 hostname and/or address) are met. So far a useful subset of
1864 post-authentication options are supported and more are expected to
1865 be added in future releases.
1866 + Add support for Diffie-Hellman group exchange key agreement with a
1867 final hash of SHA256.
1868 + Added a "ForceCommand" directive to sshd_config(5). Similar to the
1869 command="..." option accepted in ~/.ssh/authorized_keys, this forces
1870 the execution of the specified command regardless of what the user
1871 requested. This is very useful in conjunction with the new "Match"
1872 option.
1873 + Add a "PermitOpen" directive to sshd_config(5). This mirrors the
1874 permitopen="..." authorized_keys option, allowing fine-grained
1875 control over the port-forwardings that a user is allowed to
1876 establish.
1877 + Add optional logging of transactions to sftp-server(8).
1878 + ssh(1) will now record port numbers for hosts stored in
1879 ~/.ssh/known_hosts when a non-standard port has been requested
1880 (closes: #50612).
1881 + Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a
1882 non-zero exit code) when requested port forwardings could not be
1883 established.
1884 + Extend sshd_config(5) "SubSystem" declarations to allow the
1885 specification of command-line arguments.
1886 + Replacement of all integer overflow susceptible invocations of
1887 malloc(3) and realloc(3) with overflow-checking equivalents.
1888 + Many manpage fixes and improvements.
1889 + Add optional support for OpenSSL hardware accelerators (engines),
1890 enabled using the --with-ssl-engine configure option.
1891 + Tokens in configuration files may be double-quoted in order to
1892 contain spaces (closes: #319639).
1893 + Move a debug() call out of a SIGCHLD handler, fixing a hang when the
1894 session exits very quickly (closes: #307890).
1895 + Fix some incorrect buffer allocation calculations (closes: #410599).
1896 + ssh-add doesn't ask for a passphrase if key file permissions are too
1897 liberal (closes: #103677).
1898 + Likewise, ssh doesn't ask either (closes: #99675).
1899 - 4.6/4.6p1 (http://www.openssh.org/txt/release-4.6):
1900 + sshd now allows the enabling and disabling of authentication methods
1901 on a per user, group, host and network basis via the Match directive
1902 in sshd_config.
1903 + Fixed an inconsistent check for a terminal when displaying scp
1904 progress meter (closes: #257524).
1905 + Fix "hang on exit" when background processes are running at the time
1906 of exit on a ttyful/login session (closes: #88337).
1907 * Update to current GSSAPI patch from
1908 http://www.sxw.org.uk/computing/patches/openssh-4.6p1-gsskex-20070312.patch;
1909 install ChangeLog.gssapi.
1910 * Build the .deb --with-ssl-engine (closes: #408027, LP: #119295).
1911 * Use LSB functions in init scripts, and add an LSB-style header (partly
1912 from Ubuntu and partly thanks to Christian Perrier; closes: #389038).
1913 * Move init script start links to S16, move rc1 stop link to K84, and
1914 remove rc0 and rc6 stop links altogether (the last part from Ubuntu;
1915 closes: #122188).
1916 * Emit a slightly more informative message from the init script if
1917 /dev/null has somehow become not a character device (closes: #369964).
1918 * Belatedly build-depend on zlib1g-dev (>= 1:1.2.3-1) (closes: #333447).
1919 * Merge from Ubuntu:
1920 - Build position-independent executables (only for debs, not for udebs)
1921 to take advantage of address space layout randomisation.
1922 - If building on Ubuntu, add /sbin, /usr/sbin, and /usr/local/sbin to
1923 the default path.
1924 * Use ${binary:Version} rather than ${Source-Version} in openssh-server ->
1925 openssh-client dependency.

1996 * Drop versioning on ssh/ssh-krb5 Replaces, as otherwise it isn't
1997 sufficient to replace conffiles (closes: #402804).
1998 * Make GSSAPICleanupCreds a compatibility alias for
1999 GSSAPICleanupCredentials. Mark GSSUseSessionCCache and
2000 GSSAPIUseSessionCredCache as known-but-unsupported options, and migrate
2001 away from them on upgrade.
2002 * It turns out that the people who told me that removing a conffile in the
2003 preinst was sufficient to have dpkg replace it without prompting when
2004 moving a conffile between packages were very much mistaken. As far as I
2005 can tell, the only way to do this reliably is to write out the desired
2006 new text of the conffile in the preinst. This is gross, and requires
2007 shipping the text of all conffiles in the preinst too, but there's
2008 nothing for it. Fortunately this nonsense is only required for smooth
2009 upgrades from sarge.

2075 time expired (closes: #389995).

2079 portable OpenSSH, this vulnerability could theoretically lead to

2125 * New upstream release (closes: #361032).
2126 - CVE-2006-0225: scp (as does rcp, on which it is based) invoked a
2127 subshell to perform local to local, and remote to remote copy
2128 operations. This subshell exposed filenames to shell expansion twice;
2129 allowing a local attacker to create filenames containing shell
2130 metacharacters that, if matched by a wildcard, could lead to execution
2131 of attacker-specified commands with the privilege of the user running
2132 scp (closes: #349645).
2133 - Add support for tunneling arbitrary network packets over a connection
2134 between an OpenSSH client and server via tun(4) virtual network
2135 interfaces. This allows the use of OpenSSH (4.3+) to create a true VPN
2136 between the client and server providing real network connectivity at
2137 layer 2 or 3. This feature is experimental.
2138 - Reduce default key length for new DSA keys generated by ssh-keygen
2139 back to 1024 bits. DSA is not specified for longer lengths and does
2140 not fully benefit from simply making keys longer. As per FIPS 186-2
2141 Change Notice 1, ssh-keygen will refuse to generate a new DSA key
2142 smaller or larger than 1024 bits.
2143 - Fixed X forwarding failing to start when the X11 client is executed in
2144 background at the time of session exit.
2145 - Change ssh-keygen to generate a protocol 2 RSA key when invoked
2146 without arguments (closes: #114894).
2147 - Fix timing variance for valid vs. invalid accounts when attempting
2148 Kerberos authentication.
2149 - Ensure that ssh always returns code 255 on internal error
2150 (closes: #259865).
2151 - Cleanup wtmp files on SIGTERM when not using privsep.
2152 - Set SO_REUSEADDR on X11 listeners to avoid problems caused by
2153 lingering sockets from previous session (X11 applications can
2154 sometimes not connect to 127.0.0.1:60xx) (closes:
2155 https://launchpad.net/bugs/25528).
2156 - Ensure that fds 0, 1 and 2 are always attached in all programs, by
2157 duping /dev/null to them if necessary.
2158 - Xauth list invocation had bogus "." argument.
2159 - Remove internal assumptions on key exchange hash algorithm and output
2160 length, preparing OpenSSH for KEX methods with alternate hashes.
2161 - Ignore junk sent by a server before it sends the "SSH-" banner.
2162 - Many manual page improvements.
2163 - Lots of cleanups, including fixes to memory leaks on error paths and
2164 possible crashes.
2165 * Update to current GSSAPI patch from
2166 http://www.sxw.org.uk/computing/patches/openssh-4.3p2-gsskex-20060223.patch
2167 (closes: #352042).
2168 * debian/rules: Resynchronise CFLAGS with that generated by configure.
2169 * Restore pam_nologin to /etc/pam.d/ssh; sshd no longer checks this itself
2170 when PAM is enabled, but relies on PAM to do it.
2171 * Rename KeepAlive to TCPKeepAlive in default sshd_config
2172 (closes: #349896).
2173 * Rephrase ssh/new_config and ssh/encrypted_host_key_but_no_keygen debconf
2174 templates to make boolean short descriptions end with a question mark
2175 and to avoid use of the first person.

2276 credentials. This code is only built in openssh-krb5, not openssh, but
2277 I mention the CVE reference here anyway for completeness.
2278 - Add a new compression method ("Compression delayed") that delays zlib
2279 compression until after authentication, eliminating the risk of zlib
2280 vulnerabilities being exploited by unauthenticated users. Note that
2281 users of OpenSSH versions earlier than 3.5 will need to disable

2388 * New upstream release.
2389 - Normalise socket addresses returned by get_remote_hostname(), fixing
2390 4-in-6 mapping issues with AllowUsers et al (closes: #192234).
2391 * Take upstream's hint and disable the unsupported USE_POSIX_THREADS
2392 (closes: #295757, #308868, and possibly others; may open other bugs).
2393 Use PAM password authentication to avoid #278394. In future I may
2394 provide two sets of binaries built with and without this option, since
2395 it seems I can't win.
2396 * Disable ChallengeResponseAuthentication in new installations, returning
2397 to PasswordAuthentication by default, since it now supports PAM and
2398 apparently works better with a non-threaded sshd (closes: #247521).
2399 * openssh-server Suggests: rssh (closes: #233012).
2400 * Change libexecdir to /usr/lib/openssh, and fix up various alternatives
2401 and configuration files to match (closes: #87900, #151321).
2402 * Fix up very old sshd_config files that refer to /usr/libexec/sftp-server

2410 - Port-forwarding specifications now take optional bind addresses, and
2411 the server allows client-specified bind addresses for remote port
2412 forwardings when configured with "GatewayPorts clientspecified"
2413 (closes: #87253, #192206).
2414 - ssh and ssh-keyscan now support hashing of known_hosts files for
2415 improved privacy (CAN-2005-2666). ssh-keygen has new options for
2416 managing known_hosts files, which understand hashing.
2417 - sftp supports command history and editing support using libedit
2418 (closes: #287013).
2419 - Have scp and sftp wait for the spawned ssh to exit before they exit
2420 themselves, allowing ssh to restore terminal modes (closes: #257130).
2421 - Improved the handling of bad data in authorized_keys files,
2422 eliminating fatal errors on corrupt or very large keys; e.g. linefeeds
2423 in keys only produce errors in auth.log now (closes: #220726).
2424 - Add "command mode" to ssh connection multiplexing (closes: #303452).
2425 - Mention $HOME/.hushlogin in sshd(8) FILES section (closes: #163933).
2426 * Make gnome-ssh-askpass stay above other windows (thanks, Liyang HU;
2427 closes: #296487).
2428 * Remove obsolete and unnecessary ssh/forward_warning debconf note.
2429 * Hurd build fixes (although sshd still doesn't work):
2430 - Restore X forwarding fix from #102991, lost somewhere along the way.
2431 - Link with -lcrypt.
2432 - Link with -lpthread rather than -pthread.
2433 - Don't build ssh-askpass-gnome on the Hurd, until GNOME is available to
2434 satisfy build-dependencies.
2435 * Drop workaround for #242462 on amd64; it's been fixed properly upstream.
2436 * Enable HashKnownHosts by default. This only affects new entries; use
2437 'ssh-keygen -H' to convert an entire known_hosts file to hashed format.
2438 * Note in ssh_config(5) that the SetupTimeOut option is Debian-specific
2439 (closes: #307069).
2440 * debconf template translations:
2441 - Update Czech (thanks, Miroslav Kure; closes: #298744).

2550 common functionality; it didn't seem worth creating yet another package
2551 for this. openssh-client is priority standard, openssh-server optional.
2552 * New transitional ssh package, priority optional, depending on
2553 openssh-client and openssh-server. May be removed once nothing depends
2554 on it.
2555 * When upgrading from ssh to openssh-{client,server}, it's very difficult
2556 for the maintainer scripts to find out what version we're upgrading from
2557 without dodgy dpkg hackery. I've therefore taken the opportunity to move
2558 a couple of debconf notes into NEWS files, namely ssh/ssh2_keys_merged
2559 and ssh/user_environment_tell.
2560 * Add a heuristic to try to make sure the sshd_config upgrade to >= 3.7
2561 happens even though we don't know what version we're upgrading from.
2562 * Remove /etc/ssh/sshd_not_to_be_run on purge of openssh-server. For now
2563 (until sarge+2) it's still honoured to avoid breaking existing
2564 configurations, but the right approach is now to remove the

2735 - New PAM implementation based on that in FreeBSD. This runs PAM session
2736 modules before dropping privileges (closes: #132681, #150968).
2737 - Since PAM session modules are run as root, we can turn pam_limits back
2738 on by default, and it no longer spits out "Operation not permitted" to
2739 syslog (closes: #171673).
2740 - Password expiry works again (closes: #153235).
2741 - 'ssh -q' suppresses login banner (closes: #134589).
2742 - sshd doesn't lie to PAM about invalid usernames (closes: #157078).
2743 - ssh-add prints key comment on each prompt (closes: #181869).
2744 - Punctuation formatting fixed in man pages (closes: #191131).
2745 - EnableSSHKeysign documented in ssh_config(5) (closes: #224457).
2746 * Add 'UsePAM yes' to /etc/ssh/sshd_config on upgrade from versions older
2747 than this, to maintain the standard Debian sshd configuration.
2748 * Comment out PAMAuthenticationViaKbdInt and RhostsAuthentication in
2749 sshd_config on upgrade. Neither option is supported any more.
2750 * Privilege separation and PAM are now properly supported together, so
2751 remove both debconf questions related to them and simply set it
2752 unconditionally in newly generated sshd_config files (closes: #228838).
2753 * ServerAliveInterval implemented upstream, so ProtocolKeepAlives is now a
2754 compatibility alias. The semantics differ slightly, though; see
2755 ssh_config(5) for details.
2756 * Implement SSH1 support for ServerAliveInterval using SSH_MSG_IGNORE. As
2757 documented in ssh_config(5), it's not as good as the SSH2 version.

2931 the whole thing, and remove the directory if that leaves it empty

2933 * ssh has depended on debconf for some time now with no complaints, so:
2934 - Simplify the postinst by relying on debconf being present. (The absent
2935 case was buggy anyway.)
2936 - Get rid of "if you have not installed debconf" text in README.Debian,
2937 and generally update the "/usr/bin/ssh not SUID" entry.
2938 * More README.Debian work:
2939 - Reorganize into "UPGRADE ISSUES" and "OTHER ISSUES", in an effort to
2940 make it easier for people to find the former. The upgrade issues
2941 should probably be sorted by version somehow.
2942 - Document X11UseLocalhost under "X11 Forwarding" (closes: #150913).

2963 - ssh-copy-id prints usage when run without arguments (closes: #71376).

2990 previously it was completely wrong anyway.
2991 * Find out whether /etc/ssh/sshd_not_to_be_run exists and set the debconf
2992 question's default using that information, rather than using debconf as
2993 a registry. Other solutions may be better in the long run, but this is
2994 at least correct (thanks, Matthew Woodcraft; closes: #84725).
2995 * Stop using pam_lastlog, as it doesn't currently work well as a session
2996 module when privilege separation is enabled; it can usually read
2997 /var/log/lastlog but can't write to it. Instead, just use sshd's
2998 built-in support, already enabled by default (closes: #151297, #169938).

3002 * When restarting via the init script, check for sshd_not_to_be_run after
3003 stopping sshd (idea from Tomas Pospisek; closes: #149850).

3058 - ssh-agent is installed setgid to prevent ptrace() attacks. The group
3059 actually doesn't matter, as it drops privileges immediately, but to
3060 avoid confusion the postinst creates a new 'ssh' group for it.

3856 -> ssh-nonfree -> openssh. Without these, debconf remembered
3857 the old answer, config didn't force asking it, and preinst always

3861 users, people who currently suffer from "can't upgrade" may need
3862 to run apt-get install ssh twice. Did not do the same for

23 This is the portable version of OpenSSH, a free implementation of
24 the Secure Shell protocol as specified by the IETF secsh working
25 group.
26 .
27 Ssh (Secure Shell) is a program for logging into a remote machine
28 and for executing commands on a remote machine.
29 It provides secure encrypted communications between two untrusted
30 hosts over an insecure network. X11 connections and arbitrary TCP/IP
31 ports can also be forwarded over the secure channel.
32 It can be used to provide applications with a secure communication
33 channel.
34 .
35 This package provides the ssh, scp and sftp clients, the ssh-agent
36 and ssh-add programs to make public key authentication more convenient,
37 and the ssh-keygen, ssh-keyscan, ssh-copy-id and ssh-argv0 utilities.
38 .
39 In some countries it may be illegal to use any encryption at all
40 without a special permit.

10The Debian-specific parts of the package were initially derived from the
11original ssh package, which has since been renamed as ssh-nonfree.

13The Debian patch is distributed under the terms of the GPL, which you
14can find in /usr/share/common-licenses/GPL-2.
15
16In addition, as a special exception, Matthew Vernon gives permission
17to link the code of the Debian patch with any version of the OpenSSH
18code which is distributed under a license identical to that listed in
19the included Copyright file, and distribute linked combinations
20including the two. You must obey the GNU General Public License in

23file, but you are not obligated to do so. If you do not wish to do
24so, delete this exception statement from your version.

26The upstream source for this package is a combination of the ssh
27branch that is being maintained by the OpenBSD team (starting from
28the last version of SSH that was distributed under a free license),
29and porting work by Damien Miller <damien@ibs.com.au> to get it
30working on Linux. Other people also contributed to this, and are
31credited in /usr/share/doc/ssh/README.

1This package was debianized by Philip Hands <phil@hands.com> on 31 Oct 1999
2(with help from Dan Brosemer <odin@linuxfreak.com>)

4It was downloaded from here:
5 ftp://ftp.fu-berlin.de/unix/security/openssh/openssh-2.3.0p1.tar.gz

7worldwide mirrors are listed here:

10The Debian-specific parts of the package were initially derived from the
11original ssh package, which has since been renamed as ssh-nonfree.
12
13The Debian patch is distributed under the terms of the GPL, which you
14can find in /usr/share/common-licenses/GPL-2.
15
16In addition, as a special exception, Matthew Vernon gives permission
17to link the code of the Debian patch with any version of the OpenSSH
18code which is distributed under a license identical to that listed in
19the included Copyright file, and distribute linked combinations
20including the two. You must obey the GNU General Public License in
21all respects for all of the code used other than OpenSSH. If you
22modify this file, you may extend this exception to your version of the
23file, but you are not obligated to do so. If you do not wish to do
24so, delete this exception statement from your version.
25
26The upstream source for this package is a combination of the ssh
27branch that is being maintained by the OpenBSD team (starting from
28the last version of SSH that was distributed under a free license),
29and porting work by Damien Miller <damien@ibs.com.au> to get it
30working on Linux. Other people also contributed to this, and are
31credited in /usr/share/doc/ssh/README.

79OpenSSH provides end-to-end encrypted replacement of applications such as
80telnet, rlogin, and ftp.
81Unlike these legacy applications, OpenSSH never passes anything
82(including username and password) over the wire in unencrypted form, and
83provides host authentication, to verify that you really are talking to
84the system that you think you are and that no one else can take over
85that session.
86
87<p>
88The OpenSSH suite includes the
89<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a>
90program which replaces rlogin and telnet, and
91<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a>
92which replaces
93<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rcp&amp;sektion=1">rcp(1)</a> and
94<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ftp&amp;sektion=1">ftp(1)</a>.
95OpenSSH has also added
96<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> and
97<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a>
98which implement an easier solution for file-transfer. This is based upon the
99<a href="http://www.openssh.org/txt/draft-ietf-secsh-filexfer-02.txt">secsh-filexfer</a> IETF draft.
100
101
102<p><strong>OpenSSH consists of a number of programs.</strong>
103
104<ul>
105<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a> - Server program run on the server machine. This listens for connections from client machines, and whenever it receives a connection, it performs authentication and starts serving the client.
106Its behaviour is controlled by the config file <i><a
107href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">
108sshd_config(5)</a></i>.
109<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a> - This is the client program used to log into another machine or to execute commands on the other machine. <i>slogin</i> is another name for this program.
110Its behaviour is controlled by the global config file <i><a
111href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
112ssh_config(5)</a></i> and individual users' <i>$HOME/.ssh/config</i> files.
113<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a> - Securely copies files from one machine to another.
114<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a> - Used to create Pubkey Authentication (RSA or DSA) keys (host keys and user authentication keys).
115<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-agent&amp;sektion=1">ssh-agent(1)</a> - Authentication agent. This can be used to hold RSA keys for authentication.
116<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-add&amp;sektion=1">ssh-add(1)</a> - Used to register new keys with the agent.
117<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a> - SFTP server subsystem.
118<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> - Secure file transfer program.
119<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keyscan&amp;sektion=1">ssh-keyscan(1)</a> - gather ssh public keys.
120<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign&amp;sektion=8">ssh-keysign(8)</a> - ssh helper program for hostbased authentication.

123<h3>Downloading</h3>
124
125<p>
126The most recent version of OpenSSH is included with the current
127distribution of <a href="http://www.openbsd.org/">OpenBSD</a>, and
128installed as part of a basic install.
129
130<p>
131Today, most other operating systems include some version of OpenSSH
132(often re-badged or privately labeled), so most users can immediately
133use it.
134However, sometimes the included versions are quite old, and missing
135features of the current release of OpenSSH, and you may wish to install
136the current version, or install it on one of the few OSs that lacked it,
137and where the OS publisher does not make a modern version available.
138You may also wish to use OpenSSH on your embedded application.

146<h2><a name= "1.2">1.2 - Why should it be used?</a></h2>
147
148<p>
149OpenSSH is a suite of tools to help secure your network
150connections. Here is a list of features:
151
152
153<ul>
154 <li>Strong authentication. Closes several security holes (e.g., IP, routing, and DNS spoofing).
155 <li>Improved privacy. All communications are automatically and transparently encrypted.
156 <li>Secure X11 sessions. The program automatically sets DISPLAY on the server machine, and forwards any X11 connections over the secure channel.
157 <li>Arbitrary TCP/IP ports can be redirected through the encrypted channel in both directions (e.g., for e-cash transactions).
158 <li>No retraining needed for normal users.
159 <li>Never trusts the network. Minimal trust on the remote side of the connection. Minimal trust on domain name servers. Pure RSA authentication never trusts anything but the private key.
160 <li>Client RSA-authenticates the server machine in the beginning of every connection to prevent trojan horses (by routing or DNS spoofing) and man-in-the-middle attacks, and the server RSA-authenticates the client machine before accepting <i>.rhosts</i> or <i>/etc/hosts.equiv</i> authentication (to prevent DNS, routing, or IP-spoofing).
161 <li>Host authentication key distribution can be centrally by the administration, automatically when the first connection is made to a machine.
162 <li>Any user can create any number of user authentication RSA keys for his/her own use.
163 <li>The server program has its own server RSA key which is automatically regenerated every hour.
164 <li>An authentication agent, running in the user's laptop or local workstation, can be used to hold the user's RSA authentication keys.
165 <li>The software can be installed and used (with restricted functionality) even without root privileges.
166 <li>The client is customizable in system-wide and per-user configuration files.
167 <li>Optional compression of all data with gzip (including forwarded X11 and TCP/IP port data), which may result in significant speedups on slow connections.
168 <li>Complete replacement for rlogin, rsh, and rcp.
169</ul>
170
171<p>
172Currently, almost all communications in computer networks are done
173without encryption. As a consequence, anyone who has access to any
174machine connected to the network can listen in on any communication.
175This is being done by hackers, curious administrators, employers,
176criminals, industrial spies, and governments. Some networks leak off
177enough electromagnetic radiation that data may be captured even from a
178distance.
179
180
181<p>
182When you log in, your password goes in the network in plain
183text. Thus, any listener can then use your account to do any evil he
184likes. Many incidents have been encountered worldwide where crackers
185have started programs on workstations without the owner's knowledge
186just to listen to the network and collect passwords. Programs for
187doing this are available on the Internet, or can be built by a
188competent programmer in a few hours.
189
190
191<p>
192Businesses have trade secrets, patent applications in preparation,
193pricing information, subcontractor information, client data, personnel
194data, financial information, etc. Currently, anyone with access to
195the network (any machine on the network) can listen to anything that
196goes in the network, without any regard to normal access restrictions.
197
198
199<p>
200Many companies are not aware that information can so easily be
201recovered from the network. They trust that their data is safe
202since nobody is supposed to know that there is sensitive information
203in the network, or because so much other data is transferred in the
204network. This is not a safe policy.

208
209<p>
210Even though OpenSSH is developed on
211<a href="http://www.openbsd.org/">OpenBSD</a> a wide variety of
212ports to other operating systems exist. The portable version of OpenSSH
213is headed by <a href="mailto:djm@openbsd.org">Damien Miller</a>.
214For a quick overview of the portable version of OpenSSH see

216Currently, the supported operating systems are:
217
218
219<ul>
220 <li>OpenBSD
221 <li>NetBSD
222 <li>FreeBSD
223 <li>AIX

240<h2><a name= "1.4">1.4 - What about copyrights, usage and patents?</a></h2>
241<p>
242The OpenSSH developers have tried very hard to keep OpenSSH free of any
243patent or copyright problems. To do this, some options had to be
244stripped from OpenSSH. Namely support for patented algorithms.
245
246<p>
247OpenSSH does not support any patented transport algorithms. In SSH1 mode,
248only 3DES and Blowfish are available options. In SSH2 mode, only 3DES,
249Blowfish, CAST128, Arcfour and AES can be selected.
250The patented IDEA algorithm is not supported.
251
252<p>
253OpenSSH provides support for both SSH1 and SSH2 protocols.
254
255<p>
256Since the RSA patent has expired, there are no restrictions on the use
257of RSA algorithm using software, including OpenBSD.

282
283<h2><a name= "2.1">2.1 - Why does ssh/scp make connections from low-numbered ports.</a></h2>
284<p>
285The OpenSSH client uses low numbered ports for rhosts and rhosts-rsa
286authentication because the server needs to trust the username provided by
287the client. To get around this, you can add the below example to your
288<i>ssh_config</i> or <i>~/.ssh/config</i> file.
289
290
291<blockquote>
292<table border=0 width="800">

298</table>
299</blockquote>
300
301<p>
302Or you can specify this option on the command line, using the <b>-o</b>
303option to

305

313</table>
314</blockquote>
315
316<h2><a name= "2.2">2.2 - Why is the ssh client setuid root?</a></h2>
317
318<p>
319In conjunction with the previous question, (<a href="#2.1">2.1</a>)
320OpenSSH needs root authority to be able to bind to low-numbered ports to
321facilitate <i>rhosts authentication</i>.
322A privileged port is also required for rhosts-rsa authentication to older
323SSH releases.
324
325<p>
326Additionally, for both <i>rhosts-rsa authentication</i> (in protocol
327version 1) and <i>hostbased authentication</i> (in protocol version 2)
328the ssh client needs to access the <i>private host key</i> in order to
329authenticate the client machine to the server.
330OpenSSH versions prior to 3.3 required the <code>ssh</code> binary to be
331setuid root to enable this, and you may safely remove it if you don't
332want to use these authentication methods.
333
334<p>
335Starting in OpenSSH 3.3, <code>ssh</code> is not setuid by default. <a
336href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign">ssh-keysign</a>,
337is used for access to the private hosts keys, and ssh does not use privileged
338source ports by default. If you wish to use a privileged source port, you must
339manually set the setuid bit on <code>ssh</code>.
340
341<h2><a name= "2.3">2.3 - Why does SSH 2.3 have problems interoperating with OpenSSH 2.1.1?</a></h2>
342
343<p>
344SSH 2.3 and earlier versions contain a flaw in their HMAC implementation.
345Their code was not supplying the full data block output from the digest,
346and instead always provided 128 bits. For longer digests, this caused
347SSH 2.3 to not interoperate with OpenSSH.
348
349<p>
350OpenSSH 2.2.0 detects that SSH 2.3 has this flaw. Recent versions of SSH
351will have this bug fixed. Or you can add the following to
352SSH 2.3 <i>sshd2_config</i>.
353
354

365<h2><a name= "2.4">2.4 - Why does OpenSSH print: Dispatch protocol error: type 20</a></h2>
366
367<p>
368Problems in interoperation have been seen because older versions of
369OpenSSH did not support session rekeying. However the commercial SSH 2.3
370tries to negotiate this feature, and you might experience connection
371freezes or see the error message &quot;<b>Dispatch protocol error:
372type 20 </b>&quot;.
373To solve this problem, either upgrade to a recent OpenSSH release or
374disable rekeying by adding the following to your commercial SSH 2.3's
375<i>ssh2_config</i> or <i>sshd2_config</i>.
376
377
378<blockquote>

391The old versions of SSH used a patented algorithm to encrypt their

393<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a>

416<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a>
417program contained a bug which caused it to occasionally generate Pubkey
418Authentication (RSA or DSA) keys which had their Most Significant Bit
419(MSB) unset. Such keys were advertised as being full-length, but are
420actually, half the time, smaller than advertised.
421
422<p>
423OpenSSH will print warning messages when it encounters such keys. To rid
424yourself of these message, edit your <i>known_hosts</i> files and replace the
425incorrect key length (usually "1024") with the correct key length
426(usually "1023").
427
428<h2><a name= "2.7">2.7 - X11 and/or agent forwarding does not work.</a></h2>
429
430<p>
431Check your <i>ssh_config</i> and <i>sshd_config</i>. The default
432configuration files disable authentication agent and X11 forwarding. To
433enable it, put the line below in <i>sshd_config</i>:
434
435<blockquote>

457</blockquote>
458
459<p>
460X11 forwarding requires a working <a

462>xauth(1)</a> binary. On OpenBSD this is in the <i>xbase</i> file
463set but will probably be different on other platforms. For OpenSSH
464Portable, xauth must be either found at configure time or specified
465via <b>XAuthLocation</b> in sshd_config(5) and ssh_config(5).
466
467<p>
468Note on agent interoperability: There are two different and
469incompatible agent forwarding mechanisms within the SSH2 protocol.
470OpenSSH has always used an extension of the original SSH1 agent
471requests, however some commercial products use a different, non-free
472agent forwarding protocol. This means that agent forwarding cannot
473be used between OpenSSH and those products.
474

476<b>NOTE:</b> For users of Linux Mandrake 7.2, Mandrake modifies the

514
515<p>
516sftp and/or scp may fail at connection time if you have shell
517initialization (.profile, .bashrc, .cshrc, etc) which produces output
518for non-interactive sessions. This output confuses the sftp/scp client.

534
535<h2><a name= "2.10">2.10 - Will you add [foo] to scp?</a></h2>
536
537<p>
538Short Answer: no.
539
540<p>
541Long Answer: scp is not standardized. The closest thing it has to a
542specification is "what rcp does". Since the same command is used on both ends
543of the connection, adding features or options risks breaking interoperability with other
544implementations.
545
546<p>
547New features are more likely in sftp, since the protocol is standardized
548(well, a <a href="http://www.ietf.org/html.charters/OLD/secsh-charter.html">
549draft standard</a>), extensible, and the client and server are decoupled.
550
551<h2><a name= "2.11">2.11 - How do I use port forwarding?</a></h2>
552
553<p>
554If the remote server is running sshd(8), it may be possible to
555``tunnel'' certain services via ssh. This may be desirable, for
556example, to encrypt POP or SMTP connections, even though the software
557does not directly support encrypted communications. Tunnelling uses
558port forwarding to create a connection between the client and server.
559The client software must be able to specify a non-standard port to
560connect to for this to work.
561
562<p>
563The idea is that the user connects to the remote host using ssh,
564and specifies which port on the client's machine should be used to
565forward connections to the remote server. After that it is possible
566to start the service which is to be encrypted (e.g. fetchmail, irc)
567on the client machine, specifying the same local port passed to
568ssh, and the connection will be tunnelled through ssh. By default,
569the system running the forward will only accept connections from
570itself.
571
572<p>
573The options most relevant to tunnelling are the -L and -R options,
574which allow the user to forward connections, the -D option, which
575permits dynamic port forwarding, the -g option, which permits other
576hosts to use port forwards, and the -f option, which instructs ssh
577to put itself in the background after authentication. See the <a
578href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1"
579>ssh(1)</a> man page for further details.
580
581<p>
582This is an example of tunnelling an IRC session from client machine
583``127.0.0.1'' (localhost) to remote server ``server.example.com'':
584
585<blockquote>
586<table border=0 width="800">
587 <tr>
588 <td nowrap bgcolor="#EEEEEE">
589<b>ssh -f -L 1234:server.example.com:6667 server.example.com sleep 10<br>
590irc -c '#users' -p 1234 pinky 127.0.0.1</b>
591 </td>
592 </tr>
593</table>
594</blockquote>
595
596<p>
597This tunnels a connection to IRC server server.example.com, joining
598channel ``#users'', using the nickname ``pinky''. The local port used
599in this example is 1234. It does not matter which port is used, as
600long as it's greater than 1023 (remember, only root can open sockets on
601privileged ports) and doesn't conflict with any ports already in use.
602The connection is forwarded to port 6667 on the remote server, since
603that's the standard port for IRC services.
604
605<p>
606The remote command ``sleep 10'' was specified to allow an amount
607of time (10 seconds, in the example) to start the service which is to
608be tunnelled. If no connections are made within the time specified,
609ssh will exit. If more time is required, the sleep(1) value can be
610increased appropriately or, alternatively, the example above could
611be added as a function to the user's shell. See ksh(1) and csh(1)
612for more details about user-defined functions.
613
614<p>
615ssh also has an -N option, convenient for use with port forwarding:
616if -N is specified, it is not necessary to specify a remote command
617(``sleep 10'' in the example above). However, use of this option
618causes ssh to wait around for ever (as opposed to exiting after a
619remote command has completed), and the user must take care to manually
620kill(1) the process afterwards.
621
622<h2><a name= "2.12">2.12 - My ssh connection freezes or drops out after N minutes of inactivity.</a></h2>
623
624<p>
625This is usually the result of a packet filter or NAT device
626timing out your TCP connection due to inactivity. You can enable
627<b>ClientAliveInterval</b> in the server's <i><a
628href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">

631href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
632ssh_config</a></i> (the latter is available in OpenSSH 3.8 and newer).
633
634<p>
635Enabling either option and setting the interval for less than the time
636it takes to time out your session will ensure that the connection is
637kept "fresh" in the device's connection table.

662</p>
663
664<blockquote>
665SSH-2.0-OpenSSH_3.9
666</blockquote>
667
668<p>
669This information is used by clients and servers to enable protocol
670compatibility tweaks to work around changed, buggy or missing features in
671the implementation they are talking to. This protocol feature checking is
672still required at present because versions with incompatibilities are still
673in wide use.

677
678<h2><a name= "3.1">3.1 - Spurious PAM authentication messages in logfiles.</a></h2>
679
680<p>
681The portable version of OpenSSH will generate spurious authentication
682failures at every login, similar to:
683
684
685<blockquote>
686<table border=0 width="800">
687 <tr>
688 <td nowrap bgcolor="#EEEEEE">
689&quot;<b>authentication failure; (uid=0) -&gt; root for sshd service</b>&quot;
690 </td>
691 </tr>
692</table>
693</blockquote>
694
695<p>
696These are generated because OpenSSH first tries to determine whether a
697user needs authentication to login (e.g. empty password). Unfortunately
698PAM likes to log all authentication events, this one included.
699
700<p>
701If it annoys you too much, set &quot;<b>PermitEmptyPasswords no</b>&quot;
702in <i>sshd_config</i>. This will quiet the error message at the expense
703of disabling logins to accounts with no password set.
704This is the default if you use the supplied <i>sshd_config</i> file.
705
706<h2><a name= "3.2">3.2 - Empty passwords not allowed with PAM authentication.</a></h2>
707
708<p>
709To enable empty passwords with a version of OpenSSH built with PAM you
710must add the flag nullok to the end of the password checking module
711in the <i>/etc/pam.d/sshd</i> file. For example:
712
713<blockquote>
714<table border=0 width="800">
715 <tr>
716 <td nowrap bgcolor="#EEEEEE">
717auth required/lib/security/pam_unix.so shadow nodelay nullok
718 </td>
719 </tr>
720</table>
721</blockquote>
722
723<p>
724This must be done in addition to setting &quot;<b>PermitEmptyPasswords
725yes</b>&quot; in the <i>sshd_config</i> file.
726
727<p>
728There is one caveat when using empty passwords with PAM authentication:
729PAM will allow any password when authenticating an account with an empty
730password. This breaks the check that
731<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a>
732uses to determine whether an account has no password set and grant
733users access to the account regardless of the policy specified by
734<b>PermitEmptyPasswords</b>. For this reason, it is recommended that you
735do not add the <b>nullok</b> directive to your PAM configuration file
736unless you specifically wish to allow empty passwords.

743Large delays (more than 10 seconds) are typically caused by a problem with
744name resolution:
745<ul>
746<li>Some versions of glibc (notably glibc 2.1 shipped with Red Hat 6.1)
747can take a long time to resolve "IPv6 or IPv4" addresses from domain
748names. This can be worked around with by specifying <b>AddressFamily
749inet</b> option in <i>ssh_config</i>.</li>
750
751<li>There may be a DNS lookup problem, either at the client or server.
752You can use the <code>nslookup</code> command to check this on both client
753and server by looking up the other end's name and IP address. In
754addition, on the server look up the name returned by the client's
755IP-name lookup. You can disable most of the server-side lookups by
756setting <b>UseDNS no</b> in <i>sshd_config</i>.</li>
757</ul>
758
759<p>
760Delays less than 10 seconds can have other causes.
761
762<ul>
763
764<li>OpenSSH releases prior to 3.8 had an <i>moduli</i> file with
765moduli that were just smaller than what sshd would look for, and
766as a result, sshd would end up using moduli significantly larger
767than requested, which resulted in a speed penalty. Replacing the
768<i>moduli</i> file will resolve this (note that in most cases this
769file will not be replaced during an upgrade and must be replaced
770manually).</li>
771
772<li>OpenSSH releases prior to 3.8 had a flaw in <code>ssh</code> that
773would cause it to request moduli larger than intended (which when
774combined with the above resulted in significant slowdowns).
775Upgrading the client to 3.8 or higher will resolve this issue.</li>
776
777<li>If either the client or server lack a kernel-based random number
778device (eg Solaris &lt; 9, AIX &lt; 5.2, HP-UX &lt; 11.11) and no
779substitute is available (eg <a href=
780"ftp://ftp.ayamura.org/pub/prngd/">prngd</a>) it's possible that
781one of the programs called by <code>ssh-rand-helper</code> to
782generate entropy is hanging. This can be investigated by running
783it in debug mode:

845<h2><a name= "3.5">3.5 - Password authentication doesn't work (eg on Slackware 7.0 or Red Hat 6.x)</a></h2>
846
847<p>
848If the password is correct password the login is still denied, the
849usual cause is that the system is configured to use MD5-type passwords
850but the
851<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=crypt&amp;sektion=3"
852>crypt(3)</a> function used by sshd doesn't understand them.
853
854<p>
855Affected accounts will have password strings in <i>/etc/passwd</i>
856or <i>/etc/shadow</i> that start with <b>$1$</b>.
857If password authentication fails for new accounts or accounts with
858recently changed passwords, but works for old accounts, this is the
859likely culprit.
860
861<p>
862The underlying cause is that some versions of OpenSSL have a crypt(3)
863function that does not understand MD5 passwords, and the link order of
864sshd means that OpenSSL's crypt(3) is used instead of the system's.
865OpensSSH's configure attempts to correct for this but is not always
866successful.
867
868<p>
869There are several possible solutions:
870
871<ul>
872<li>
873<p>
874Enable sshd's built-in support for MD5 passwords at build time.
875

881 </td>
882 </tr>
883</table>
884</blockquote>
885
886This is safe even if you have both types of encryption as sshd will
887select the correct algorithm for each account automatically.
888
889<li>
890<p>
891If your system has a separate libcrypt library (eg Slackware 7) then you
892can manually add -lcrypt to the LIBS list so it's used instead of
893OpenSSL's:
894
895<blockquote>
896<table border=0 width="800">
897 <tr>
898 <td nowrap bgcolor="#EEEEEE">

902</table>
903</blockquote>
904
905<li>
906<p>
907If your platforms supports PAM, you may configure sshd to use it
908(see <a href= "#3.15" >section 3.15</a>). This will mean that sshd will
909not verify passwords itself but will defer to the configured PAM modules.

925path to search on the server. This option replaces the default path,
926so you need to specify all the current directories on your path as well
927as where you have installed scp. For example:

938
939<p>
940Note that configuration by the server's admin will take precedence over the

942<i>/etc/profile</i>, PATH in <i>/etc/environment</i> on AIX, or (for 3.7p1 and

1.TH GNOME-SSH-ASKPASS 1
2.SH NAME
3gnome\-ssh\-askpass \- prompts a user for a passphrase using GNOME
4.SH SYNOPSIS
5.B gnome\-ssh\-askpass
6.SH DESCRIPTION
7.B gnome\-ssh\-askpass
8is a GNOME-based passphrase dialog for use with OpenSSH.
9It is intended to be called by the
10.BR ssh\-add (1)
11program and not invoked directly.
12It allows
13.BR ssh\-add (1)
14to obtain a passphrase from a user, even if not connected to a terminal
15(assuming that an X display is available).
16This happens automatically in the case where
17.B ssh\-add
18is invoked from one's
19.B ~/.xsession
20or as one of the GNOME startup programs, for example.
21.PP
22In order to be called automatically by
23.BR ssh\-add ,
24.B gnome\-ssh\-askpass
25should be installed as
26.IR /usr/bin/ssh\-askpass .
27.SH "ENVIRONMENT VARIABLES"
28The following environment variables are recognized:
29.TP
30.I GNOME_SSH_ASKPASS_GRAB_SERVER
31Causes
32.B gnome\-ssh\-askpass
33to grab the X server before asking for a passphrase.
34.TP
35.I GNOME_SSH_ASKPASS_GRAB_POINTER
36Causes
37.B gnome\-ssh\-askpass
38to grab the mouse pointer using
39.IR gdk_pointer_grab ()
40before asking for a passphrase.
41.PP
42Regardless of whether either of these environment variables is set,
43.B gnome\-ssh\-askpass
44will grab the keyboard using
45.IR gdk_keyboard_grab ().
46.SH AUTHOR
47This manual page was written by Colin Watson <cjwatson@debian.org>
48for the Debian system (but may be used by others).
49It was based on that for
50.B x11\-ssh\-askpass
51by Philip Hands.

1Template: openssh-server/permit-root-login
2Type: boolean
3Default: false
4_Description: Disable SSH password authentication for root?
5 Previous versions of openssh-server permitted logging in as root over SSH
6 using password authentication. The default for new installations is now
7 "PermitRootLogin without-password", which disables password authentication
8 for root without breaking systems that have explicitly configured SSH
9 public key authentication for root.
10 .
11 This change makes systems more secure against brute-force password
12 dictionary attacks on the root user (a very common target for such
13 attacks). However, it may break systems that are set up with the
14 expectation of being able to SSH as root using password authentication. You
15 should only make this change if you do not need to do that.

4Subject: Various Debian-specific configuration changes
5
6ssh: Enable ForwardX11Trusted, returning to earlier semantics which cause
7fewer problems with existing setups (http://bugs.debian.org/237021).
8
9ssh: Set 'SendEnv LANG LC_*' by default (http://bugs.debian.org/264024).
10
11ssh: Enable HashKnownHosts by default to try to limit the spread of ssh
12worms.
13
14ssh: Enable GSSAPIAuthentication and disable GSSAPIDelegateCredentials by
15default.
16
17sshd: Refer to /usr/share/doc/openssh-server/README.Debian.gz alongside
18PermitRootLogin default.
19
20Document all of this, along with several sshd defaults set in

4Subject: GSSAPI key exchange support
5
6This patch has been rejected upstream: "None of the OpenSSH developers are
7in favour of adding this, and this situation has not changed for several
8years. This is not a slight on Simon's patch, which is of fine quality, but
9just that a) we don't trust GSSAPI implementations that much and b) we don't
10like adding new KEX since they are pre-auth attack surface. This one is
11particularly scary, since it requires hooks out to typically root-owned
12system resources."
13
14However, quite a lot of people rely on this in Debian, and it's better to
15have it merged into the main openssh package rather than having separate
16-krb5 packages (as we used to have). It seems to have a generally good
17security history.

4Subject: Various keepalive extensions
5
6Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported
7in previous versions of Debian's OpenSSH package but since superseded by
8ServerAliveInterval. (We're probably stuck with this bit for
9compatibility.)
10
11In batch mode, default ServerAliveInterval to five minutes.
12
13Adjust documentation to match and to give some more advice on use of
14keepalives.

4Subject: Don't check the status field of the OpenSSL version
5
6There is no reason to check the version of OpenSSL (in Debian). If it's
7not compatible the soname will change. OpenSSH seems to want to do a
8check for the soname based on the version number, but wants to keep the
9status of the release the same. Remove that check on the status since
10it doesn't tell you anything about how compatible that version is.

4Subject: Include the Debian version in our identification
5
6This makes it easier to audit networks for versions patched against security
7vulnerabilities. It has little detrimental effect, as attackers will
8generally just try attacks rather than bothering to scan for
9vulnerable-looking version strings. (However, see debian-banner.patch.)

4Subject: Reduce severity of "Killed by signal %d"
5
6This produces irritating messages when using ProxyCommand or other programs
7that use ssh under the covers (e.g. Subversion). These messages are more
8normally printed by the calling program, such as the shell.
9
10According to the upstream bug, the right way to avoid this is to use the -q
11option, so we may drop this patch after further investigation into whether
12any software in Debian is still relying on it.

4Subject: Restore TCP wrappers support
5
6Support for TCP wrappers was dropped in OpenSSH 6.7. See this message
7and thread:
8
9 https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-April/032497.html
10
11It is true that this reduces preauth attack surface in sshd. On the
12other hand, this support seems to be quite widely used, and abruptly
13dropping it (from the perspective of users who don't read
14openssh-unix-dev) could easily cause more serious problems in practice.
15
16It's not entirely clear what the right long-term answer for Debian is,
17but it at least probably doesn't involve dropping this feature shortly
18before a freeze.

4Subject: ssh(1): Refer to ssh-argv0(1)
5
6Old versions of OpenSSH (up to 2.5 or thereabouts) allowed creating symlinks
7to ssh with the name of the host you want to connect to. Debian ships an
8ssh-argv0 script restoring this feature; this patch refers to its manual
9page from ssh(1).

4Subject: Accept obsolete ssh-vulnkey configuration options
5
6These options were used as part of Debian's response to CVE-2008-0166.
7Nearly six years later, we no longer need to continue carrying the bulk
8of that patch, but we do need to avoid failing when the associated
9configuration options are still present.

4Subject: "LogLevel SILENT" compatibility
5
6"LogLevel SILENT" (-qq) was introduced in Debian openssh 1:3.0.1p1-1 to
7match the behaviour of non-free SSH, in which -q does not suppress fatal
8errors. However, this was unintentionally broken in 1:4.6p1-2 and nobody
9complained, so we've dropped most of it. The parts that remain are basic
10configuration file compatibility, and an adjustment to "Pseudo-terminal will
11not be allocated ..." which should be split out into a separate patch.

4Subject: Allow harmless group-writability
5
6Allow secure files (~/.ssh/config, ~/.ssh/authorized_keys, etc.) to be
7group-writable, provided that the group in question contains only the file's
8owner. Rejected upstream for IMO incorrect reasons (e.g. a misunderstanding
9about the contents of gr->gr_mem). Given that per-user groups and umask 002
10are the default setup in Debian (for good reasons - this makes operating in
11setgid directories with other groups much easier), we need to permit this by
12default.

42.Nm
43replaces the old ssh command-name as hostname handling.
44If you link to this script with a hostname then executing the link is
45equivalent to having executed ssh with that hostname as an argument.
46All other arguments are passed to ssh and will be processed normally.

48See
49.Xr ssh 1 .
50.Sh FILES
51See
52.Xr ssh 1 .
53.Sh AUTHORS
54OpenSSH is a derivative of the original and free
55ssh 1.2.12 release by Tatu Ylonen.

1This package contains a Gnome based implementation of ssh-askpass
2written by Damien Miller.
3
4It is split out from the main package to isolate the dependency on the
5Gnome and X11 libraries.
6
7It was packaged for Debian by Philip Hands <phil@hands.com>.

3 The normal openssh-server and openssh-client packages in Debian now
4 include full GSSAPI support, including key exchange. This package is
5 now only a transitional package that depends on openssh-server and
6 openssh-client and configures openssh-server for GSSAPI authentication
7 if it wasn't already.
8
9 You can now simply install openssh-server and openssh-client directly
10 and remove this package. Just make sure that /etc/ssh/sshd_config
11 contains:
12
13 GSSAPIAuthentication yes
14 GSSAPIKeyExchange yes
15
16 if you want to support GSSAPI authentication to your ssh server.
